Thanks for your help ########## - I appreciate the time and effort in your response. All understood.
Can someone clarify this for me please ... (before I look like an idiot when I visit my Toyota dealer next week!!!) My D4D is not suffering from any performance issues and the tolerances are all within the acceptable tolerance of +/- 3.0% both hot and cold. However, Toyota are replacing the injectors because of the noise from the engine when its cold and under acceleration. So tell me - is that 'spray can rattle' noise the injectors operating or is that the leakage from the injector seat?
The a diesel specialist (who suggested all my injectors be replace also) says that injectors in common-rail diesels squirt up to 5 times per combustion cycle, as compared to a old-tech mechanical injector which only fires once per combustion. The reason for the multiple injection is because 1) it helps to achieve a smooth operation 2) more efficient combustion 3) lower emissions. So this additional work these new style injectors do suggests they do up to 5 times as much work and are simply worn out because of the low sulphur diesels in Australia providing less lubrication. Am I right here?
Is the injector seat leakage a different issue? Or is this the cause for the rattle (& carbon issues)?
Someone is lamens terms break it down for me please. I guess dirty diesel is another cause for failure.
